Title: Method for preventing surface deterioration of soft rock in excavation work
Inventor: ISHIDA RYOJI
IPC: E02D3/00
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the surface of a soft rock and put it in a subsequent process by excavating a rock bed of the soft rock and applying coating of polymer cement by spraying or brush application to the surface of the soft rock exposed on surface ground. SOLUTION: The rock bed of a soft rock is excavated to apply coating of polymer cement to the surface of the soft rock exposed on surface ground. The polymer cement is made a paste mixing a resin in cement without need of sand and applied by spraying or brush application. Foundation of dam foundation, a road, a rail and the like is excavated in a normal excavation method. Next, immediately after the excavation, coating is applied by the polymer cement to the surface of the soft rock exposed on the surface ground by the excavation. Concrete is directly placed in the coating to enter a subsequent process. Thereby sufficient adhesive strength is obtained not to need removal of the coating, and the concrete is directly placed in the coating of the polymer cement to simplify a working process.

Title: Liquid jet controller
Inventor: ITO KEIICHI
IPC: E03D9/08
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To securely prevent hot liquid heated to a high temperature from jetting out. SOLUTION: A temperature-discrimination signal STC showing whether the temperature of cleaning water in a tank 14 has exceeded an upper limit temperature or not, is output from an comparator 27. A control signal HA is generated by a microcomputer 30 on the basis of the signal STC and an operation signal WS changing over the jet motion of the liquid. The conductive conditions of an electric source supply controller 43 is controlled on the basis of the signal HA to control the electric power supply to the motor 48. And also the conductive conditions of electric source supply controller 52 is controlled on the basis of the signal STC to control the electric power supply to the motor 48.  Even if an incorrect signal HA is generated and the controller 43 is switched on, since the controller 52 is not put on, on the basis of the signal STC, the electric power supply to the motor 48 is prohibited and hence, the cleaning water which has exceeded an upper limit temperature is securely prevented from jetting out.

Filed: 1994-07-27
Abstract: PURPOSE:To prevent hydrogen from being diffused into a gate insulating film with an antireflection film constituted of an SiOn thin film being kept existing by letting a gate electrode include a titanium layer. CONSTITUTION:On an Si substrate 1 where element isolation regions 2 and a gate insulating film 3 are formed, a gate electrode 9 which is constituted of a polysilicon layer 4, a Ti layer 5 and a titanium silicide layer 6 which is put between the other two layers 4 and 5 is formed. On the gate electrode 9, an antireflection film 7 constituted of an SiOn system thin film is deposited in the same pattern as the gate electrode 9. Due to this structure, a hot carrier resistance is remarkably increased compared with the conventional MOS transistor which has no Ti layer 5 in the gate electrode 9. Therefore, even if the antireflection films 7, 18 which are constituted of Sign system thin films are kept existing, hydrogen is prevented by the Ti layer 5 included in the gate electrode 9 from reaching the gate insulating film 3.

Title: Method for half toning document
Inventor: HARRINGTON STEVEN J
IPC: H04N1/60
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a color image error diffusing method utilizing vector error diffusion capable of simplifying vector error diffusion calculation. SOLUTION: In the method, error diffusion is not directly applied to colors (c), (m), (y) but is directly applied to the total and differences of these colors (c), (m), (y). In order to determine which pixel has black, white or a color based on the evaluation of s=c+m+y, t=c-× and u=m-y, (s) is used at first. The values of (t) and (u) are used for determining an primary color, a secondary color or black. Then the terms (t), (u) of differences are used for determining which primary color or secondary color is to be printed out. In the method, error diffusion can be attained only by three channels. Thereby it is unnecessary to calculate an inter-color distance and a simple judgement tree selects a color to be outputted in each pixel. A white or black pixel can be selected by twice determination and one of other six colors can be selected by four times determination.
